Application of the velocity field method to stability analysis of earth reinforcement

The velocity field method was applied to stability analysis of the earth reinforcement. The effect of the reinforcing material in soils was considered by the internal dissipation energy in the velocity field method. The additional shear resistance of the reinforcing material mobilized at the slip plane was evaluated as a direct link between the reinforcement force and the increase of the confining pressure due to pull-out force. The internal dissipation energy of the reinforcing material was considered using the direct reinforcement material force. As a workable example, this paper presents the active earth pressure of reinforced earth retaining wall by applying the velocity field method.
